MACHINE- FOR tliRYlNG VARNISHED LABELS..

SPECIFICATION forming part of Letters Patent No. 335,771, dated February 9, 1886.

Application filed May Al, 1985. Serial No. 164,389. (No model.)

To all whom, it may con/cern:

Be it known that l, CARL RAI-issiiorim, of the city and county of San Francisco, State of California, have invented an Improvementin Machines forI-Iandling and Drying Newly- Varnished Labels; and I hereby declare the following to be a full, clear, and exact description of the same.

My invention relates to a new and useful machine, the object ot' which is to handle and dry wet or newly-varnished prints, sheets, labels, die.; and my invention consists ot' an endless serpentine carrier consisting of side chains and parallel spaced transverse bars adapted to receive and carry labels, me., power-transmitting mechanism for driving the carrier, and a clutch mechanism operated and controlled by the varnishing-press l'or regulating and controlling the periodical movement of the carrier, a novel arrangement of swinging flies for feeding the labels, an endless transverse belt loncated between the tlies and adapted to receive the labels and deliver them to the carrier, and a mechanism operated and controlledA by the press l'or periodically moving the belt, all ot' which, together with the various details ot' construction, l shall hereiliafter particularly describe.

rllhe particular application ot' my invention 3o is the handling ol" newly-varnished labels. These are pnt through the varnishing-press rapidly, and are too wet to handle without injury immediately after being varnished, and much time is wasted in attempting to take them by hand and remove them to any drying apparatus or elsewhere; but by means of the machine which I have invented the labels are not touched by the operator, but are carried by the mechanism of the varnishing-press 4o through intermediate devices to the carrier,

and are moved along by it for a length of time equal to the extent of the carrier, so that when they come out at the other end they are comparatively dry and can be easily handled'.

Referring to the accompanying` drawings, Figure l is a perspective view showing my machine'. Fig. 2 is a perspective view of the carrier. Fig. 3 is a perspective detail showing the attachments of one of the bars to side 5o chain ofthe carrier. Fig. t is a plan of the clutch' mechanism controlling the periodical movement ofthe carrier. Fig. 5 is an elevation of the mechanism on the varnishing-press for operating the clutch mechanism in Fig. 4. Fig. 6 is a vertical section of Fig. 5. Fig. 7 55 is an elevation of the mechanism by which the endless belt which moves the labels laterally is operated. Fig, 8 is aview of the clutch mechanism by which the machine is stopped and started.

The carrier, as will be seen by Fig. 2, consists of two endless side chains, A, between which extend transverse bars A. These chains pass up over chain-pulleys a andi down over smooth pulleys c', the course being a serpen- 65 .tine one, returning` horizontally underneath to the point of beginning. These pulleys are all mounted in a suitable trame-work, I3, which is shown in Fig. l. The dimensions of the carrier are governed by the length of time 7o which it is desired the labels shall take in passing through from the feed end to the discharge end. This should be long enough to give them an opportunity to dry, either wholly or partially, the accomplishment of which object may be assisted by any suitable arrangement of steam pipes or lans or other drying apparatus to be located within the framework B.

The bars A are journaled loosely in suitable 8o bearings in the chains, as shown in Fig. 3, wherebythey may accommodate themselves to their constantly-changing positions throughout the course ot' travel of the carrier. It is intended that the travel of the carrier shall be periodical, so that it shall reinainat a state of rest, with one ot' its bars in position to receive the labels, until said bar shall receive its complement, and then to make its movement to carry the labels one step in advance Q0 and bring the succeeding bar in position for a fresh set of labels. To accomplish this result,

I have the following mechanism, which is shown in Fig. l, and more in detail in Fig. 4.

C is a pulley, which is adapted t0 receive 95 the driving-belt from any suitable source of power. This pulley is located on the side of the frame-work B, and has a shaft, c. Upon the inner end ofthe shaft is a loose pinion, c', which carries on its side a toothed clutch, c2. me The pinion meshes with a gear, D, on a counter-shaft, cl, which carries also a chain-pulley,

' spring, Z.

D', from which a belt, d', Fig. l, eXtends to a pulley, E, on a shaft, e, which extends transversely across vthe front of the frame B, and forward of the first line of side chains and bars of the carrier, so that it does not interfere with the labels.

Upon the shaft e is a beveled pinion, e', Fig. 1, which meshes with a beveled pinion, j, on the end of a shaft, F. This shaft carries a number of beveled pinions,f, which mesh with beveled pinions g on the small counter-shafts, which also carry the pulleys a, over which the chains of the carrier pass. A shaft similar to F, carrying a series of beveled pinions similar to f', which mesh with beveled pinions similar to g, are located on the other side of the carrier, and are driven by means of a beveled pinion on the other end of the shaft e, which meshes with a beveled pinion similar tof. By this mechanism the carrier is driven from both sides, and also has a number of points where the power is applied directly, so that the strain of driving is not so great as if it were driven from but one chain-pulley.

Feathered upon the shaft c is a groove-faced disk, H, in the groove of which a collar, h, is loosely fitted, and is set by a screw, h. A spring, I, upon the shaft c has a tendency to push the feathered disk H over into engagement with the clutch ci, the adjacent face of the disk being correspondingly shaped to form a clutch, h2, as shown in Fig. 4. The collar h has a projection, h3, with the side of which a beveled-faced lug, d2, upon the gear D is adaptedto engage. The collar is formed with a lever-extension, J, pivoted at j, and having its other end adapted to fit in a notch, k, made in the end of a vertically-swinging lever, K, which is pivoted at k'. Under the other end of the lever K bears the forward end of a long lever, L, pivoted atl, and is influenced by a It has attached to its other end a wire orl cord, l. Referring now to Fig. 5, it will be seen that this wire or cord extends downwardly, and is attached to the forward end of a lever, M,which is pivoted to a bracket y on the side of the varnishing-press.

N is the varnishing-press, the upper cylinder or roll, n, of which is provided, as shown in Fig. 5, with a disk, n', on one end. This disk carries a pin, n2. Mounted upon a counter-shaft is a toothed wheel, O, here shown as .having ten teeth, with one of which the pin n is adapted to engage at each rotation of the cylinder n. Upon the side of the toothed wheel O is a diametrical lever,`o, having in each end a pin or stud, o. Upon the lever N is a pin or stud, m, with which the pins o of the diametrical lever o are adapted to engage.

The operation of this mechanism is as follows: At every rotation of the cylinder n of the varnishing-press the pin n comes in conp tact with and turns the toothed wheel O one comes in contact with the pin m of the lever M. This forces down said lever, pulling the cord Z and drawing down one end of the lever L,by which the other end is raised. This end bearing under the inner end of the lever K, raises that end of said lever, whereby its outer end is lowered away from its engagement with the lever J. As this engagement was the resistance to the spring I, it now being relieved, said spring forces the clutch-disk H into engagement with the clutch c2, whereby power is transmitted th rough the gearing described to the carrier. It makes but a short movement, however, for in a revolution of the gear D its beveled lug d2, comingin contact with the projecting end h3 of the collar h, forces said end outward, thus throwing the free end of the lever J into its engagement with the lever K, whereby the clutch-disk H is removed from the clutch c2, and is held in such disengaged position by reason of the engagement of the lever J with the notch k of lever K. This mechanism is so adjusted that the periodical movement ofthe carrier takes place after five labels have gone through the press, and therefore the length of the carrier-bars is also regulated to receive conveniently five labels. Vhen arbar has received the ve labels, the motion of the carrier takes place, and a fresh bar is presented for the recept-ion of more labels.

Hinged to the rear of the press is a ily, P, which is adapted to receive the labels from the traveling cords or strings Q. Hinged to the 'framework B is a fly, R, which is adapted to receive the forward half of the label from the ily P. These iiies rise approximately simultaneously to receive each label, about onehalf lying on each fly, and they lower approximately together, thus folding the label over the cross-belt, which I shall hereinafter describe.

The fly P is operated by the following mechanism: Upon the end of the cylinder-shaft, Fig. 8, is loosely mounted a gear, S, with which meshes a gear, s, on the main drivingshaft s'. The gear Sis provided with a clutch, s2, with which a clutch, t, feathered on the cylinder-shaft, engages. This clutch carries a pulley, T, from which a belt, t', extends to a pulley, u, on a cross-shaft, U, under the press. Upon this shaft is a cam, u', having a camgroove, u2, in its side, which receives a stud, o, on the lower end of a rod, V, the upper end of which is connected with a bail, t', which is itself connected with the fly P by links c2. The ily R is operated by means of the eccentric w on shaft U, over which plays an eccentric-strap, W, the rod of which is connected IOO IIO

above with one end of a lever, w', pivoted at w2 and connected by a rod, w, at its rear end with a crank-arm, o, on the shaft r of the fly R. These devices should be so arranged that the movement of fly P will be a little in advance of ily R, so that they can accommodate themselves to the travel of the labels, each receiving it at the proper time and allowing evenly.

it to fall over the `receiving-belt gently and Secured to a short arm of frame B are arms b, which carry in their ends the stops b. These consist of downwardlyextending fingers passing between the lingers of ily'R. They are secured in the arms b by means of Set-screws, whereby they may be vertically adjusted, and the arms b are themselves secured in a like manner for a similar purpose. The object of the stops b is to limit the advance of the label and fix it in such a position that it shall hang with about an equal portion on each side.

Across the front of the frame B is the endless receiving-belt X. This consists, preferably, of two parallel and spaced ropes passing over double-faced pulleys x, at each side ofthe frame. They are located in the vertical plane of the front receiving-bars, which are adapted to rise between said ropes.

A periodical movement is given to the receivingbelt by the following mechanism: Referring to Fig. 7,it will be seen that the near pulley :1: is provided with a springpawl, ir. This pulley is loose upon its shaft. Y' is a ratchetewheel, fast on the j iulley-shaft, and

having a pinion, y, with which engages a pivoted segmental gear, y', operated by a lever, z/Q, secured to'its body. Upon the end ofshaft ll is a short crank, y, having a pin, y", upon which is slotted a bar, yf", the other end of which is pivoted to one end of a lever, y, pivoted at li/l. \Vith the other end of the lever Y is connected a bar, Q/S, the upper end of which New, the crank is connected with lever y. yf, as it moves through one-half its revolution, pulls down the bar gif and the forward end of lever y raising its rear end. This raises the lever j, which, through the segmental. gear y and pinion y, causes the rota-tion of the l ratchet in adirection against the pawl, where ried over out ofthe way ofthe next one.

In order to throw t-he whole machine out ol' or into gear, I have the rocking treadle-shaft Z,connected by a short crank, @,and bar .c/ with the clutch-lever e?, which embraces in the usual manner the feathered clutch t. By operating the shaft Z the clutch t is thrown into or out of engagement with the clutch s?, whereby the machine is started or stopped. l The carryingstrings Q are driven from a drum, q, rotated by a belt, q', from the shaft U.v

A brief description of the operation of the entire device will conduce to a better understanding cf the machine. The clutch t being thrown into engagement with the clutch sl and the machine started,the operator passes a label,

through the rolls or cylinders. It is thence carried by the strings Q to and upon the ily P,which has just risen to or a little above the level of the belt X. About one-half of the label passes across the belt onto the fly R,which has risen to receive it, and the ngers b stop it in such a position that it lies with about equal portions on each ily, and the belt X passing under its center. The flies now move down,allowing the label to'hang on belt X,and almost at the same moment the belt travels laterally, carrying the label with it out of the way of the succeeding one. Five labels are thus received by the belt, when the engagement oli' the lever o with the lever M takes place. Power is by these means transmitted through spring-lever L to disengage lever J, whereby the spring I is allowed to throw the clutch if" into engagement with clutch ci, thereby transmitting the power from pulley G through the shafts, gears, and belts described to the chain-pulleys a, by which the carrier is driven. As the carriermoves its cross-bar A', which lies immediately under the carrierbelt X,rises between the two parts of said belt and carries the labels up with it. By the time the succeeding bar of the carrierA reaches its position under the belt X the beveled stud d on gear D has come toits engagement with the projection h ol' the collanextension h of lever J, whereby said lever is forced back toits engagement with lever K, in which position the clutch 71.2 is out of engagement with clutch ci and the carrier stops. The belt X is again supplied, and a repetition of the operation described takes place. The labels are conveyed through the serpentine course of the carrier, and are laken olf the other end, while the bars continue forward Ain a horizontal course inthe lower portion of the frame B to the point of beginning. The serpentine course of the car rier is of advantage in creating a draft or movement of air as the labels move past each other, thereby drying them, even without the aid of other apparatus.

It is obvious that this machine may be applied to other purposes than handling wet labels.

Any kind of prints which would be injured by immediate handling can be put through the machine'.
